Crysis. But not because of the game itself. I had been playing another game not long before with my Xbox 360 controller and had left it plugged in even though I was going to use my keyboard and mouse.

When Crysis kicked off the desk started shaking however I didn't realise consciously and couldn't figure out why it was so much scarier than usual. The Xbox 360 controller had force feedback turned on and was responding to the soundtrack.
